I contacted Tanchjim about their Tanchjim One's since they'd sensibly decided to go with a replaceable cable. I thought I'd ask where I can buy the official Tanchjim One replaceable cable (3.5mm, non DSP) since it's designed rather differently than many, in that the socket is quite narrow and the pins on the cable are longer than most.
I won't go through the whole conversation (much of which seemed lost in translation), but here's my final bid:
Their reply was (I've corrected the grammar a little):
Seems strange that Tanchjim, after giving their One IEM a (nontraditional) narrow socket and their cable for it a deep pin, wouldn't then sell their own cable separately (more money for Tanchjim, no?).
I'm still waiting on my 3rd party cable to see if it fits, but I have a feeling there may be some filing involved.
You'd think, since Tanchjim had gone to the trouble to make a cable replaceable, it would have been trivial to manufacture extra cables and make these available to customers (who might want spares) and not just sellers for aftercare issues. I've just been involved in a lens hood product with a push cap - for the initial order we made extra push caps to be sold separately - it seemed obvious.
